Subject: Snags and Coarse Woody Debris Spatial Data Standard
This information bulletin (IB) establishes the Oregon/Washington (OR/WA) spatial data standard for Snags and Coarse Woody Debris (SNAG_CWD) Points. The data standard defines how this type of data is to be captured in a Geographic Information System (GIS), defines attributes used, and defines coding schemes (domains). The data has been added to the corporate spatial data editing system. The data can be edited by approved field personnel following established procedures and are also available for display and analytical purposes by all users.
The SNAG_CWD represents spatial location, core attributes, treatment, and monitoring information about Snags (a tree which has been manipulated to provide wildlife habitat, can be dead or alive) and Coarse Woody Debris. Snags or coarse woody debris can be created either through timber harvest or as a stand-alone project.
This dataset is used to track corporate information regarding the characteristics of created snags and coarse woody debris. This data will allow users and managers to understand the costs, benefits and the effectiveness of different approaches to snag and coarse woody debris management. The data can be used for both regional and local planning processes.
This dataset is considered part of the Micro*Storms database, which consists of Forest Operations Inventory Vegetation Polygons, Forest Survey Polygons, and forestry treatments.
The draft data standard was made available for internal review and comment. To see comments and responses, contact Eric Hiebenthal, State Data Administrator, at 503-808-6565, or by email at ehiebent@blm.gov.
Questions about the data standard should be directed to Bruce Hollen, State Data Steward for Snags and Coarse Woody Debris Points, at 503-808-6604; Dana Baker-Allum, GIS Technical Lead for Snags and Coarse Woody Debris Points, at 503-808-6320; and Eric Hiebenthal, State Data Administrator, at 503-808-6565.
